maybe you are using PHP 5.4.24 ? there is a bug in this version, please use PHP 5.5 or 5.3 instead, thanks

I followed your advice but now I see just a blank page!

Dear forum community.
If I might be so bold to just jump in on this thread:
I have got PHP 5.4.24 and as a developper and supporter of the modified eCommerce community I tried to install PIWIK for a modified shop.
I have got the same errors as the original poster in post 1.
Is there any possibilities to get PIWIK 2.0.3 to work on PHP 5.4.24 ?
It would be not so easy to downgrade the PHP version for me.

Thanks for an advice,
cheers,
theRealAnodyne

please use the latest beta, as we have fixed this bug! Update - Analytics Platform - Matomo

Hey matt.
Thanks for the advice.
"Login as the Super User in Piwik, go to Settings > General Settings…"
The problem is that due to the mentioned errors I can’t login in PIWIK since I wasn’t even able to install it.
Is there another possibility to get the latest beta version ?

Cheers,
theRealAnodyne

May I carefully push my question ?
To avoid misunderstandings:
Since the error messages prevent me from installing PIWIK at all, I can’t follow the instructions to update to the newest beta version.

Thanks,
theRealAnodyne

Okay, I found this site and loaded down piwik-2.0.4-b12.
Everything works perfectly right now, as far as I can see.
Thanks a lot for your support.

Well, I found two more error mesages in “Settings”.
This is what the error messages say:
"Notice: Array to string conversion in /home/webdesig/public_html/internetagentur-endres.de/piwik/core/Plugin/ControllerAdmin.php on line 126 "

"Warning: sprintf(): Too few arguments in /home/webdesig/public_html/internetagentur-endres.de/piwik/core/Plugin/ControllerAdmin.php on line 126 "

Is there another place where I should post these ?

Thanks again,
the Real Anodyne

Thanks for the report! I fixed this error in git: Fix notice · matomo-org/matomo@9e9f1f8 · GitHub

Thanks, that fixed it.
Respect for this quick fix and all the work you do.
